Patients with longstanding obstructive lower urinary tract symptoms (LUTS) due to benign prostatic hypertrophy (BPH) can also develop symptoms of overactive bladder syndrome (OAB). Transurethral resection of the prostate (TURP) and Transurethral Waterjet Ablation of the Prostate (Aquablation) are amongst the gold standard surgical treatments for BPH. However, in the immediate post-operative period, TURP and Aquablation can also include OAB-like symptoms, including urinary frequency and urgency. For men with baseline OAB symptoms, this initial worsening of symptoms can be distressing. Botox is an FDA approved medication with on-label indications to treat overactive bladder. The purpose of this study is to evaluate the outcomes of men who have Botox concurrent with their TURP or Aquablation.
